SEWING-MACHINE GUIDE.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed April 21. 1900. Serial No. 13.700.

To all whom it may concern:

a Be it known that I, IsAAc STUHLiiAiv, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illiprovide a guide that will automatically yield when striking into a corner of the edge of the goods, such for instance as that which occurs in the notch of a coat lapel, thus permitting the goods to pass under the needle past such corner sufliciently far to reach the proper marginal distance for the edge stitchinfg that runs off at an angle to the right or le t.

With these ends in view my invention consists in certain features of novelty in the construction, combination and arrangement of parts by which the said objects and certain other objects hereinafter appearing are .attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a perspective view partly broken away of a sewing machine head having my improved guide applied thereto, the view being taken from the rear. Fig. 2 is an enlarged detail sec tional view taken through the upper joint of the arm which supports the guide. Fig. 3 is a detail sectional view taken through the lower joint of said arm. Fig. 4 is a plan view of the'presser foot and guide, the movable member of the presserfoot being turned up. Fig. 5 is a transverse sectional view of the presser foot with the movable member turned down. Fig. 6 is a detail sectional view of a part of-the presser foot showing the stop for limiting the upward movement of the movable portion. Fig. 7 is a transverse section taken on the line 7-7 Fig. 4. Fig. 8 is a vertical longitudinal sectional view of the guide stem and guide showing the device for locking the guide in place. Fig. 9 is a detail transverse section taken on the line 99 Fig. 8 showing the supplemental guide in its turned-up or inactive position. Fig. 10 is a similar view showing the supplemental guide turned down in its active position, and Fig. 11 is an enlarged detail sectional view of the dog for holding the gages hereinafter described.

1 represents a stem upon the outer end of which is mounted the guide proper 2 which has a straight edge or end adapted to abut against the edge of the goods 3 for guiding the same under the needle 4 and forming a line 5 of stitching very close to such edge. When a corner such as shown at 6, in the edge of the goods is reached it is evident that the guide 2 must either be withdrawn or yield to permit the goods to pass far enough under the needle to-reach the marginal distance represented by the dotted line 7 of the seam or line of stitching which turns to the right of the line 5.

In order that the guide 2 may always remain in 1place and serve to guide the needle around t e corner 6 and thus avoid the necessity of stitching around such corner by the aid of the eye alone, I make the guide 2 yield on its stem 1 so that it will move rearwardly.

a suflicient distance with the goods to enable the latter to come under the needle until the line 7 is reached. In order to accomplish this the upper side of the guide 2 is provided with a dove-tailed rib 8 which slides in the under side of the stem 1 lengthwise of the line of stitching 5 or transversely of the stem 1 and projecting u wardly from this rib 8 is a pin 9 which slides ack and forth in a transverse slot 10 formed in the stem 1 and con- 'taining a spring or cushion, 11 which bears against the pin 9 and serves to hold the guide 2 in its normal position. In order that the guide may be'firm while the straight edge is being stitched it is locked by means of a latch 12 having an eye or aperture in one end which fits down over the pin 9, its other end being pivoted at 13 to the upper side of the stem 1 and having a heel-piece 14 which bears against a spring 15 mounted on the stem 1 so that the latch will be held in lace when turned down and will also be hel d up .out of engagement when turned up. In the use of the device the latch 12 will be turned up out of the way when the corner 6 is reached, thus permitting the guide 2 to yield as required and when the corner is passed and the guide resumes its normal osition under the influence of the spring 11 t e latch 12 is again thrown down to engage the pin 9. When it is desired to run the seam 16 or to do qfiirllting or to run any seam or line of stito g at a distance from the edge of the goods, requiring the goods to be placed Lmder the guide 2, the guide is elevated by any suitable means but preferably by. the means which I shall presently describe and the goods passed under it and it is also set inwardly or towards the right so that it will be approximately over the last seam or line of stitching while the needle is in the proper place for making the next line of stitching and a supplemental guide 17 is then turned down and the goods adjusted until the last line of stitching falls directly under the point of the guide 17 when the presser foot may be lowered and the goods adjusted in the position for the next line of stitching. This supplemental guide 17 is hinged to the guide 2 by means of a pin 18 and it is so arranged that when not in use it may be turned over on top of the guide 2 as clearly shown in Fig. 9 and when desired for'use may be turned down in front of the guide 2 as shown in Fig. 10, the bottom of the mortise 19 in which the supplemental guide 2 lies being beveled at 20 to hold the guide 17 at the requisite angle and the guide 17 being slotted as shown at 21 where the pin 18 passes through it so as to yield upwardly to permit irregularities in the goods to pass.

The stem 1 passes through a pair of keepers 22 mounted on a horizontal plate 23 and projects across the bottom flanges 2425 of two independently adjustable gages 2627 each having a vertical flange 2829 provided with a notch 3031 and the stem 1 is provided with a dog 32 adapted to be dropped into either of the notches 3031 and thus hold the guide in position. As shown in Fig. l the dog 32 is in the notch 31 which holds the guide 2 in proper position for running the stitching5. When it is desired to run the next line of stitching further removed from the edge of the goods the dog 32 is lifted out and dropped into the notch 30 whose gage 26 has been previously set for the proper distance between the stitching 516. Thus it will be seen that the guide 2 may be readily changed from one position to the other and the seams on all garments will be uniform. The dog 32 is formed on a lifting head 33 provided with a stem 34 which projects downwardly through the stem 1 and has a lug 35 engaging in a socket 36 in the plate 23 for better holding'the stem 1 in position, the spring 37 being interposed between the top of a casing 38 in which the stem 34 is located,

and a pin 39 in the stem 34 for automatically pulling the stem 34 downward.

The plate 23 is supported by an arm 40 whose upper end is mounted on an eccentric 41, see Fig. 3, having a thumb head 42 and a screw 43 which passes through the lower end of an arm 44 and a nut 45 by means of which the eccentric 41 may be locked in place. By this means it will be seen that when the head 42 is turned the plate 23 will be raised and the guide 2 consequently lifted the requisite distance to permit the goods to pass under it and under the plate 23 also if desired.

The upper end of the arm 44 is pivoted between two ears 46 011 a divided collar 47 which may be clamped or otherwise secured to the sewing machine arm 48, 4t) being the pivot which supports the arm 44, and 50 is a spring which is coiled around the projecting ends of the pivot 49 and passes through perforations 51. therein and thence passes downwardly in front of the arm 44- so as to exert a normal tendency to force the arm 44 upwardly under the sewing machine arm 48, the arm 44 being curved to the contour of the under side of the arm 48 so as to .tit closely thereto while the arm 40 is curved to the contour of the under side of the arm 44 so that it may be folded closely to the under side of the arm 44 and thus bring the plate 23 and the mechanism supported. thereon up under the arm 48 and. out of the way. The spring 50 is designed to throw the arm 44 and connected parts up in the described manner as soon as the catch 52 is withdrawn. This catch 52 passes through one of the cars 46 and engages in the arm 44 as clearly shown in Fig. 2-, a coil spring 53 surrounding the catch. 52 to force it normally inward.

The presence of the guide 2 so close to the presser foot when the edge stitching 5 being made necessitates the presser foot being made in two parts so that one portion may be turned up to give place to the guide 2. iteferring to Figs. 4 to 7 inclusive, 54- represents the leg of the presser foot and 55 is the presser foot proper or stationary part secured thereto in any suitable way while 56 is the movable or hinged part. The part 56 is provided with a hub 57 which is hinged by means of a pin 58 to the side of the part 55 so that the part 56 may be turned into a vertical position as shown in Figs. 4 and. 7 to give place to the guide 2 which is moved up into close proximity to the presser foot 55 when the edge seam 5 is to be run. A coil spring 59 is passed around the boss 69 and. secured to the member 55 in any suitable way at one end while the other end. is passed downwardly and engaged under the heel of the member 56 as shown at 60 so that when the member 56 is unrestrained the spring 59 will throw it up into the position shown in Fig. 7. In order that the member 56 may be held down in position when desired I provide a latch which has a beveled head 61 arranged on the upper side of the foot member 55 and projecting slightly beyond its edge so that when the member 56 is forced downwardly it will first deflect the head 61. and then engage under it. The latch is provided with a stem 62 mounted in a keeper 63 on the upper side of the member 55 while the head 61 is mounted in a keeper 64, a coil spring 66 being interposed between the head 61 and keeper 63.

The foot member 56 is limited in its upward movement by a lug 67 formed on. the hub 57 and engaging with a lug 68 formed on a boss 69Tprojecting from the side of the member 55.

Having thus described my invention what I claim as new thereinijand desire to secure by Letters Patent is: I
